PWM - Pulse Width Modulation for DC Motor Speed and LED Brightness 2
To understand how the 74AC14 PWM circuit functions, it is essential to focus on the schematic section that includes the trimpot, diodes, capacitor, and the first inverter logic gate. Initially, when power is applied to the circuit, the capacitor is...
Consisting of a plurality of parallel MOSFET high current output linear regulator circuit MIC5158
The MIC5158 is designed to manage tasks by controlling multiple external N-channel MOSFETs in parallel, which enables high current or high power output for a linear regulator circuit. This is illustrated in the accompanying figure. The operational amplifier circuit functions...
Alternating-led-flasher
The timing components are R1, R2, and C1. C1 is a bypass capacitor used to reduce the effects of noise. At start-up, the voltage across C1 is less than the trigger level voltage (1/3 Vcc), causing the timer to be...
Sound Synchronized LED Video Tutorial
It is possible to synchronize the LEDs so that the speakers continue to play loudly while the LEDs are not always illuminated during music playback. The individual has a solid understanding of electrical concepts and is seeking a method to...
LED tilt level
This electronic level utilizes two LED indicators in place of an air bubble. When the surface tilts to the right, one LED illuminates; conversely, if it tilts to the left, the other LED illuminates. Both LEDs light up when the...
Motor speed controller with timer 555
Pulse width modulation (PWM) is a technique to control analog circuits with a digital output. PWM is used in many applications, especially to control light intensity and speed on motors. A PWM circuit makes a square wave with a variable...
Nite Rider LED Lights
IC4, C1, R1 and R2 are used for the clock pulse which is fed to both the counters IC2 and IC3 Pin 14. IC1 is a Flip Flop and is used as a switch to enable either IC2 or IC3...
Police Car Lights with LEDs
This circuit simulates the flashing strobe lights of British police cars by alternating the lights. The IC1a functions as a square wave oscillator with an adjustable frequency controlled by VR1 to achieve the desired effect.
The circuit utilizes an integrated...
PWM to vary the light intensity of a 220V bulb
A 220V bulb is connected such that one end of the relay is linked to a 220V DC source and the other end is connected to ground. The switching between these two points is controlled by a PWM output as...
